IMPROVEMENT IN SNAP-HOOKS.

Specification forming part of Letters Patent No. 179,335, dated June 27,1876; application filed February 25, 1876.

To all whom it may concern Be it known that I, GEORGE D. MOsHER,

of New Britain, in the county of Hartford lies loosely in a mortise inthe body of the snap, resting at both ends on the bottom of the mortise,and pressing near its center on a point or cam borne on the under sideof the tongue, which point or cam is almost immediately under, but atritle forward, of the pivot upon which the tongue swings.

My snap has the advantage over the common snap that it requires noriveting or other fastening to keep it in place, and it so much cheapensand simplifies the construction of snaps.

My snap differs from other snaps in not having the spring resting byboth ends on the bottom of the mortise, but having the front end restingon the bottom of the mortise, while the rear end rests in a hook borneon the under side of the butt-end of the tongue. It further difl'ers innot requiring any particular point or cam on the bottom of the tongue tobear on the spring.

My snap differs in operation from other snaps in that, first, when thetongue of my snap is opened the spring tends to shut it with aconstantly -increasing pressure, while in other snaps the spring actswith a constantlydecreasing pressure as the tongue opens; second, inother snaps the cam bearing on the springmust of necessity be so nearthe pivot of the tongue as to require a very strong spring to exert anyclosing effect whatever on the tongue, which is not the case with mysnap; third, the point or cam bearing on the spring in many other snapsmust of necessity be so near the pivot of the tongue that before thetongue is half way opened this cam will swing back of the pivot of thetongue, and the spring will then press the tongue open instead oftogether, which is not the case with my snap.

The letter a denotes the body of my snap;

I), the mortise; 0, the tongue pivoted on the .pin (1. The letter 6denotes the spring, the

front end bearing on the bottom of the mortise, and the rear end in thehook f, which is on the butt-end of the tongue, and the center of thespring, or thereabout, bearing on the rounded projection g on the underside of the tongue, and preferably directly under the pivot-pin.

I claim as my improvement- In combination, the body to, having themortise b, the pivoted tongue having hook f and bearing 9, and thespring 0, bearing at its front end on the bottom of the mortise, at itscenter on projection g, and at its rear end in hook f, substantially asdescribed.
